Unified for New Opportunities - Czech Republic - New tax forms for Clearstream Europe AG clients

In relation to the initiative Unified for New Opportunities, Czech Republic is part of the market activation wave planned in September 2026.

Between September 2026 and Q1 2027 (final closure of the accounts), Clearstream Europe AG¹ clients holding 6-series accounts will then gradually be able to move their securities to CEU or Clearstream Banking S.A. (CBL) accounts.

For the Czech market, CEU will offer the same level of tax service as CBL. Therefore, to allow clients to already prepare the required certification for their CEU account, clients are requested to refer to the following:

• Market Taxation Guide – Czech Republic for the procedures and full certification requirements. The Market Taxation Guide – Czech Republic for CEU clients will be published in due course but as CEU will offer the same level of tax services as CBL, CEU clients may refer to the CBL tax guide until the CEU tax guide has been published.
• Tax Forms - use the newly created CEU tax forms (available on the Tax Forms to use - Czech Republic page) to certify CEU accounts for the purpose of obtaining relief at source.

Impact on clients

Clients migrating their assets from 6-series to CEU accounts or settling new Czech securities in their CEU accounts must submit Czech tax certification as follows in order to document their CEU account for tax purposes:

• 6-series account not certified: Certify your CEU account by submitting the CEU tax forms as per the documentation requirements described in the Market Taxation Guide – Czech Republic; or
• 6-series account already certified: The existing certification can be duplicated to a CEU account by using the normal duplication process. Please refer to the paragraph “Tax documentation service” in Section 5.8. of the OneClearstream Client Handbook and Announcement D25032 for full details.

Clients are recommended to start the certification process immediately to allow a smooth treatment by tax operational team and avoid the risk of not being certified if onboarding new securities and must ensure to provide their certificates/duplication requests if possible by the date of the activation or no later than the deadline applicable for relief at source of the first income payment to which it applies For the usual certification deadlines, please refer to the Market Taxation Guide – Czech Republic.
